Set up narrow and stay on the lead foot for uphill chips
On a left-foot-high (uphill) chip, keep a narrow, open stance with weight on the front (left) foot and the ball either in the middle or slightly forward of middle. The most important thing is to stay in the left foot through the backswing and through-swing, because the low side lets gravity pull you back and rock you off the lead foot.
